Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  a__f(a(), b(), X) -> a__f(mark(X), X, mark(X))
     , a__c() -> a()
     , a__c() -> b()
     , mark(f(X1, X2, X3)) -> a__f(mark(X1), X2, mark(X3))

Proof Output:
  None of the processors succeeded.

           We have computed the following set of weak (innermost) dependency pairs:

             {  1: a__f^#(a(), b(), X) -> c_0(a__f^#(mark(X), X, mark(X)))
              , 2: a__c^#() -> c_1()
              , 3: a__c^#() -> c_2()
              , 4: mark^#(f(X1, X2, X3)) -> c_3(a__f^#(mark(X1), X2, mark(X3)))

             This path is subsumed by the proof of path {4}->{1}->{8}.

             This path is subsumed by the proof of path {4}->{1}->{8}.
